Thanx, btw here's some usefull random thing i found while googling dnx5120
USB Hubs
The DNX-5120 manual states that USB Hubs cannot be used with the DNX-5120; however, one user has reported that a USB Hub was successfully connected allowing the user to use an iPod as well as a USB storage device at the same time[11].
USB support
According to the Kenwood website[3], the DNX-5120 has the following limitations on files and folders stored on USB devices:
Maximum number of folder layers: 8
Maximum number of folders (per device): 255
Maximum number of files (per folder): 255
Maximum number of files (per device): 15000
Maximum number of files per playlist: 7000
However, users have found, so far, that the device is limited to a total of 135 folders[4], including all subfolders. Folders outside of this limit are inaccessible and appear in the folder list, but they are "grayed out." This limitation does not appear to apply to iPods.
Some users have also had issues with the USB device being recognized on startup. If the device is attached when the car is turned on, the device is sometimes not recognized[5][6].
Another issue with USB playback is that the device currently does not allow fast-forward or rewind of the current playing track (this is possible during playback on other media, such as CD or DVD). Full tracks may be advanced or reviewed; however, the seeking is not enabled through the currently playing track[7].
It should also be noted the maximum drive size is 32gb, formated with FAT32. Unlike the documentation states, the unit displays files in the order they were written to the drive, not alphabetical as Kenwood claims.
